I have recently discovered the joy of RSS subscriptions first hand.  Before RSS, the only way to stay informed of the news and events that interested me was to subscribe to the appropriate mailing list.  This resulted in a cluttered mail box.  Last week I downloaded an RSS news reader for OS X called Vienna, and I started subscribing to the RSS feeds of the web sites and message forums that I enjoy.  Wow, is this empowering.  No longer do I have to spend an hour surfing the web to see if there is anything new on my favourite sites – or on the Dataface forum.  Now I just have to check Vienna and see if there are any new posts.
